سؤال

Se ci serve generare dei link che siano utili per l'indicizzazione e user friendly come posso formattare l'eventuale testo che devo aggiungere al link?

Il codice per generare la stringa da aggiungere all'url sarà il seguente, bisognerà richiamare la funzione GetUrl:


public static function GetUrl($url)
{
return preg_replace('![-]+!', '-', preg_replace('/^-/', '', preg_replace('/-+$/', '', preg_replace( '/[^\p{L}\p{N}-]/u', '-',
//preg_replace("/[^A-Za-z0-9 \p{Arabic}\p{Cyrillic}\x{4E00}-\x{9FBF}\x{3040}-\x{309F}\x{30A0}-\x{30FF}\p{Han}+\x{3130}-\x{318F}\x{AC00}-\x{D7AF}-]/u", '', // => viene già fatto da preg_replace( '/[^\p{L}\p{N}-]/u'
static::RimozioneAccento(preg_replace("/(c)[\s]*(#)/i", "C-sharp", preg_replace("/(c)[\s]*(#)/i", "C-sharp", preg_replace("/&#?[a-z0-9]{2,8};/i","",$url))))))));//);
}

/// Fonte: https://developer.wordpress.org/reference/functions/remove_accents/
public static function RimozioneAccento( $string, $locale = '' ) {
if ( ! preg_match( '/[\x80-\xff]/', $string ) ) {
return $string;
}

if ( mb_check_encoding($string, 'UTF-8') ) {
